HYGIENIC APPLIANCE FOR SOUND-TRANSMITTERS.

SPECIFICATION forming part of Letters Patent No. 768,768, dated August30, 1904. Application filed January 24, 1902. Serial No. 91,119. (Nomodel.)

for Sound-Transmitters, of which the follow-v ing is a specification.

This invention relates to improvements upon hygienic appliances forsoundtransmitter mouthpieces, for which Letters Patent of the UnitedStates, No. 654,096, were granted to me July 17, 1900.

Some of the objects of the present invention are to provide superior andsimpler means for holding the hygienic stripvtaut across the mouth ofthe sound-transmitter, to increase the facility of applying said stripto the stripholder ready for use, to avoid any liability of tearing orfraying the edges of the strip, and to reduce to a minimum the contactbetween the holder and that face of the strip which is presented to theuser.

A further object is cheapness, simplicity, and increased ease ofmanufacture.

In the present appliance the holder for the axle upon which the roll ofthe hygienic strip is carried comprises two/resilient standards havingholes, respectively, in whichY the ends of the axle are'journaled. Saidstandards are preferably bowed toward each other, so that the portionaround the axle-bearing will frictionally contact with and press againstthe ends of the-roll, thereby to act as a brake to hold the same againstracing. Provision is upon the roll is uniform at all times.

Another feature oi' the invention consists.

in the construction of a member of' the stripholder, which is benttoform three walls of the tension-guide for the strip as well as a seatfor the member which forms the other .wall of the strip-guide andcutter, across the edge of which the strip is to be drawn to tear oft'the used portion thereof from time to time, as required.

The accompanying drawings illustrate this invention.

Figure I is a perspective view of the -im- -in position ready for use asit appears 'after a used portion has been torn oif. Fig. III is a sideelevation of the appliance detached. Fig. IV is a vertical mid-sectionon line IV IV, Fig. II. Fig. V'is a fragmental section `on line V V,Figs. III and IV. Fig. VI is an exaggerated plan section on line VI VI,Figs. 6o III and IV. Fig. VII is a View of the guiding and tearing platedetached. Fig. VIII is an enlarged section of one of the standards. Fig.IX is a plan of the member o of the strip-holder.

1 designates means constructed to hold and guide a portion of thehygienic strip 2 across the open end of the mouth oil thesound-transmitter e. The same may consist in a body formedof a plainstrip of sheet metal bent in 7o four members a o o Z and adapted tofasten upon the telephone or other sound-transmitter and constructed toextend ony opposite sides of'the mouthpiece thereof substantially as inthe said patented device.l The arm Z of the 75 strip-holder 1 isconstructed to form three walls of a tension-guide y for the hygienicstrip. With this object in view the end of the body is bent downward toform the tensionguide member Z in the usual manner, and said 8O member lis bent at its edges to form shoulders e, and outside said shoulders isbent upon itselt` to form plate-retainers f to hold the member 3, whichforms'the front wall ofthe also made whereby the action of the brake' .Ymiddle, as indicated at L, so thatwhen the end of the hygienic strip 2is pointed, as shown in Fig. I, it can be readily passed through theguideway formed between therplate 3 and the arm CZ. The plate 3 pressesthe sides of the strip against the memberl and holds the 95 samefriction-tight, while the greater portion oi' the strip'is free fromcontact with said "plate 3.

In order to provide a most simple and elficient means for holding therolled portion /z of the hygienic strip, a strip 4, of sheet-steel orother suitable resilient material, is bent to lit against the arm 7) andto extend from said arm in two inwardly-bowed standards j, which areprovided with holes /r to form bearings for the axle 5 of the roll ofthe hygienic strip. The holes in said standards may extend in bent slots6 in the inwardly-bowed portion 7 of the standards. Said slots pref-.erably slant downward rearwardly and thcn extend forward and terminatein undercut journal-bearings r. The purpose of this undercut is toprevent the strain of the strip 2 on the roll c' from displacing theaxle 5 when the strip is drawn downward to bring a new surface infrontof the receiver. Each of the standards j is preferably formed with aninwardly-projeeting boss S at the bearing-holes 71. 'Ihe bosses 8 areheld by the resilient standards y' against the roll, near the axisthereof, so that the frictional pressure upon the roll remains constantuntil the roll is fully unwound.

rIheplate 3 of the tension-guide 1/ is preferably furnished at its edgeswith shoulders m to lit against the projections f of the arm d toprevent the plate 3 from being forced upward by the strip 2 in the actof tearing.

a designates a rivet, fastening' the resilient strip I to the arm of thebody of the holder.

Preferably the strip will be wound in a roll upon a perforated core o,of wood, through which the axle 5 may readily be passed preparatory toapplying the strip to the holder. The bosses 8 may press against thewooden Acore o of the roll.

' In practice the hygienic strips will be put up in rolls ready forapplication to the holder and the free end p of the strip will bepointed to facilitate threadingthrough the open space g at the middle ofthe plate 3. The roll will be inserted between the standardsyl and theaxle 5 brought into the bearing t. Then the point y) of the strip willbe. inserted through the space y and the strip drawn down, so that itsedges are clasped between the plate 3 and the member (l. Vhen the userdesires to bring a new surface into position, he will draw the strip andtear it ofi in the usual way. The plate 3 is wider than the member (l,so that the lower end of the strip is left free behind the plate 3 to bedrawn down by the lingers of the user in order to again bring' a newsurface into play.

The parts of the strip -holder may be stamped and pressed from threestrips of sheet metal or other suitable material, and each of saidstrips is of a practically plain and simple form, as will readily beunderstood from the drawings.

The cost of-assembling thepartsis comparatively small owing to simpleconstruction.

9 designates gains desirably formed in the edges of the member of thebody to hold the standards y'.

s designates hole for the rivet n.
